一、集群的安裝部署
我們還是利用docker來(lái)安裝RabbitMQ集群。3分鐘安裝一個(gè)集群，開(kāi)始。
前提條件，docker安裝了docker-compose。如果沒(méi)安裝的話(huà)，參考這里
docker-compose文件參考bitnami官網(wǎng)：https://github.com/bitnami/containers/tree/main/bitnami/rabbitmq#setting-up-a-cluster
這是最簡(jiǎn)單的方式安裝一個(gè)RabbitMQ集群
docker-compose.yml如下：
version: '2'
services:
stats:
image: bitnami/rabbitmq
environment:
- RABBITMQ_NODE_TYPE=stats
- RABBITMQ_NODE_NAME=rabbit@stats
- RABBITMQ_ERL_COOKIE=s3cr3tc00ki3
ports:
- '15672:15672'
volumes:
- 'rabbitmqstats_data:/bitnami/rabbitmq/mnesia'
queue-disc1:
image: bitnami/rabbitmq
environment:
- RABBITMQ_NODE_TYPE=queue-disc
- RABBITMQ_NODE_NAME=rabbit@queue-disc1
- RABBITMQ_CLUSTER_NODE_NAME=rabbit@stats
- RABBITMQ_ERL_COOKIE=s3cr3tc00ki3
volumes:
- 'rabbitmqdisc1_data:/bitnami/rabbitmq/mnesia'
queue-ram1:
image: bitnami/rabbitmq
environment:
- RABBITMQ_NODE_TYPE=queue-ram
- RABBITMQ_NODE_NAME=rabbit@queue-ram1
- RABBITMQ_CLUSTER_NODE_NAME=rabbit@stats
- RABBITMQ_ERL_COOKIE=s3cr3tc00ki3
volumes:
- 'rabbitmqram1_data:/bitnami/rabbitmq/mnesia'
volumes:
rabbitmqstats_data:
driver: local
rabbitmqdisc1_data:
driver: local
rabbitmqram1_data:
driver: local
新建docker-compose.yml
我新建了一個(gè)目錄mycompose，進(jìn)入到這個(gè)目錄，然后用上面的yml新建一個(gè)文件
用cat命令，輸出到docker-compose.yml
[root@localhost mycompose]# cat >> docker-compose.yml << EOF
> version: '2'
>
> services:

> volumes:

> queue-ram1:
> image: bitnami/rabbitmq
> environment:
> - RABBITMQ_NODE_TYPE=queue-ram
> - RABBITMQ_NODE_NAME=rabbit@queue-ram1
> - RABBITMQ_CLUSTER_NODE_NAME=rabbit@stats
> - RABBITMQ_ERL_COOKIE=s3cr3tc00ki3
> volumes:
> - 'rabbitmqram1_data:/bitnami/rabbitmq/mnesia'
>
> volumes:
> rabbitmqstats_data:
> driver: local
> rabbitmqdisc1_data:
> driver: local
> rabbitmqram1_data:
> driver: local
> EOF
[root@localhost mycompose]# ls -al
總用量 4
drwxr-xr-x. 2 root root 32 9月 24 21:26 .
dr-xr-x---. 6 root root 254 9月 24 21:23 ..
-rw-r--r--. 1 root root 1017 9月 24 21:26 docker-compose.yml
查看文件，建好了
[root@localhost mycompose]# ls -al
總用量 4
drwxr-xr-x. 2 root root 32 9月 24 21:26 .
dr-xr-x---. 6 root root 254 9月 24 21:23 ..
-rw-r--r--. 1 root root 1017 9月 24 21:26 docker-compose.yml
在當(dāng)前目錄執(zhí)行docker-compose up
[root@localhost mycompose]# docker-compose up
執(zhí)行效果如下：
啟動(dòng)完成后，發(fā)現(xiàn)確實(shí)是啟了三個(gè)RabbitMQ的容器
[root@localhost ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

進(jìn)入其中一個(gè)容器
如上面所示，我們進(jìn)入ID為a8abe421a79a的容器。
[root@localhost ~]# docker exec -it a8a /bin/bash

如果想停止當(dāng)前集群，可以用docker-compose down命令。
常用命令如下
docker-compose [-f <arg>...] [options] [COMMAND] [ARGS...]
部分命令選項(xiàng)如下：文章來(lái)源：http://www.zghlxwxcb.cn/news/detail-730395.html
-f，–file：指定使用的 Compose 模板文件，默認(rèn)為 docker-compose.yml，可以多次指定，指定多個(gè) yml；
-p, --project-name：指定工程名稱(chēng)，默認(rèn)使用 docker-compose.yml 文件所在目錄的名稱(chēng)；
-v：打印版本并退出；
